I don't feel as thought I have to explain my actions, but I can give a general summary.
For personal reasons, I've cleared out the majority of my list. I probably like you, we're probably friends. In fact, we probably text each other or have eachother on Facebook. I didn't delete you because I dislike you in any way.
I did it for peace of mind. You are more than welcome to re-add me if you feel as though I have jilted you in some way. I assure you, my "list" here does not determine my friendship with people. I don't believe I need to have you here to be your friend, but if you feel otherwise, by all means, readd me. It's to my discretion if I accept.
As for others, we probably stopped talking a long time ago.
